My invention relates to `windowscreens comprising sections which areslidably oon-` nected for adjustment to litinwindow open-` ings ofdifferent widths, and 'has reference more particularly to the manner `offastening the screen wire into the screen frame.

n'screens` of this character, light wooden frames areemployed `in whichthe screen wire is secured,and the side strips or stiles of 1o onesection are slidably'connected with the side strips or stiles of theother section, the screen wires of the sections being overlapped, andtheoverlying edge of the screen wire `of each 'section being secured to across brace or edge binding member whichV extends be tween the Stilesand serves as a filler between the screen wire of the sections to closethe gap therebetween:

The screen wire is preferably secured tothe stiles with a strip,preferablyintegral with the stile, overlying the edge portion ofthescreen Wire and fastened down to the stile with fasteners whichengagethrough'the edge porliso tion of the screen wire. This stripisusually quite'thin and arranged at the side of the stile next to thestile of the other section with which it is slidably connected,andthefasteners are `inserted therethrough from that side. With ythisconstruction vit is not only desirable to employ fasteners whichxwillhold the strip andedge/of the screen wire securely `in place,

`but it is also important to provide fasteners of suitablecharacter and`arranged in such a manner that they will not at any time annoy the useror subject the 'light frames to excessive strains by catching orinterfering with the free andeasy sliding operation of the sections.This is accomplished in my present construction by using staples tofasten the strips in place, and the staples l are not only arranged'diagonally to therline vto `of movement of the sliding sections but thestaples of the two stiles which are slidably connected, lare arranged inopposite diagonal directions to the line' of slidingmovement, so thatthey-approaclifone'another at a suitable angle to facilitate passing andto avoid interference with one another and cramping in the slidingengagement of the sections. This also, affords an arrangement `wherebythe staples straddle the grain of with the two prongs of the staplelocated so Las to give a double connection of maximum in place; to avoidinterference by the fasteners in the sliding movement. of the sections;

to arrange the fasteners so thatthey have a reciprocal guiding action inpassingyand in general to provide al simple, convenient `andeconomicalfastening for accomplishing the above objects. f

similar to that of Patent No. 97 2,481, of October 11, 1910, to Sprague,and comprises two sections 1 and 2 of screen wire supported in Vseparateframes which are slidably connect ed, with the screen in sections 1`andQ over l lapping, to vary the size of the screen to tit in differentwindow openings.

VThe frame of the screen section 1 comprises two Stiles 3-3 connected attheir outer ends to an end rail l in any convenientmannen and theframeof the screen section 2comprises the stiles 5&5, which are likewise connected at their outer'ends to theend -rail 6. The frames of the twoseotionsareoflike widthand length, and havetheirv stiles formed ,forsliding. interengagement, the stiles 5 being provided in the innerfaces,neX t to the The screen shown and described hereinis 2 `Bnn'r n.HINKLE, on HILLsnAILnfMIonIGAN, Asssrelvon` To HILLSDALE scnnnnV OOM-the` wood *ciu stiles 3 with longitudinally extending rab bets orgrooves 7 having an undercut recess 8 as illustrated in Fig. 4, whilethe stiles are provided on the inner faces next to the stiles 5 with alongitudinal rib 9 fitting to slide freely in the groove or channel 7and a laterally extending i'iange 10 lil-rewise fitting in the under cutrecess 8 of the stile 5. 'Ihus when the inner ends of the two frameparts are brought together, the ribs and fianges 9-10 will fit into andslide within the corresponding grooves and undercut recesses 7 8, theengagement of the fianges 10 in the undercut recesses 8 preventingthetwo frame parts from separating laterally and the ribs 9 in the grooves7 holding the frames in constant parallel relation.

For securing the screen wire sect-ions 1 and 2 in the frames, the inneredge of each of the stiles 3-3 and have formed therein a deep narrowslot or lerf 11 adapted to receive the edge of the wire screen cloth.These slots or kei-fs, which are merely wideenough to receive the edgeof the screen wire freely therein in assembling, are located quite closeto the inner er adjoining faces of the stiles 3 and 5, so as to providea thin lip or strip 12, which is adapted to be clamped down by suitablefasteners against the screen in the slot or kerf 11, and to provide adefinite lineI along which the lip 12 may bend when clamped down and toavoid breaking or splitting of the wood at undesirable places, the lipis preferably scored at 13 along the inner extremity thereof or at theinner edge of the slot or lerf 11 shown in Fig. if.`

The fasteners for securing the edge of the screen wire in the slots 11are passedthrough the lips 12 from the inside to anchor the ends thereofin the thicker portion of the wood and also to avoid impairing the outerfinn ished surface of the screen. The inner ends of the fasteners aretherefore located on the contiguous sliding surfaces of the screen framesections. and if not fully driven in, or if they loosen up, are likelyto VAcatch and interfere with the desired free and easy sliding movementof the frame sections, thereby f causing annoyance and imposingexcessive strain on the light marginal frames.

In order to insure a more substantial fastening of the screen wire inthe frames, and to avoid catching` of the fasteners even though they arenot fully driven in. or loosen up somewhat. I employ staples 14 and 15respectively on the sections 1 and 2 which are wide enough to straddle asubstantial portion of the lip 12, and I arrange these staplesdiagonally so that the loop or bight portion 16 extents across the grainof the wood with the prongs 17 thereof in different strata to minimizethe danger of splitting.

Moreover I arrange the staples lll and 15 of the two adjoining stiles inopposite diagonal directions as shown in Figs. 1 and 6, so that inpassing over one another they do not approach and pass in parallelrelation but at a suitable angle as shown in Fig. 6, so that thecorresponding ends come together first. The staples are formedpreferably of round wire, and in bendino the prongs or arms 17downwardly from the center or bight portion 16 and driving the staples,round bends 18 are formed at the corners and the center portion usuallyarched somewhat as shown in Fig. 7., so that the ends of the bightportion 16 or corners 18 are usually pretty well embedded in the lip 12,and by arranging the staples of the two stiles in opposite diagonaldirections the rounded and depressed portions 18 of the opposite staplescome together first, so that they start to pass quite readily eventhough the staples are not fully driven in, and the criss cross orangular arrangement of the bight portion 16 affords a reciprocal guidingaction to facilitate passing of the staples over one another.

The screen wire may be secured to the end rails 4f and 6 in anyconvenient manner, for example by inserting in a slot 19, the ends ofwhich receive tenons of the stiles 3 or 5 with a strip 20 filling in theeXtra space in the slot between the stiles and held in place byfasteners 21 which pass through the end portion of the screen wire inthe slot. The remote edges of the screen sections 1 and 2, which overlapone another, are each confined in a folded metal marginal binding strip22, the

ends of which are secured in the kerfs or slots 11 of the respectivestiles 3-3 or 5 5 to afford a cross brace for the frame, and the portionof this marginal binding 22, between the stiles is bent into an angularform as shown in Fig. 5. to stiffen the cross brace and afford a flange23 to close the space between the screens and prevent insects enteringtherethrough.

With this construction the screen wire not only may be securely fastenedin light wooden frames, but the annoyance and excessive strainsoccasioned by the fasteners along the stiles catching and interferingwith the sliding of the sections is avoided, as the fasteners ride overone another freely and easily even though they are not fully driven inor have pulled out slightly.
